Hello, Can anyone share any experiences with: http://spfbl.net/en/dnsbl/ It seems that they list servers that are used to file complaints with Spamcop and other blacklists - as "spam" servers... They do not de-list these servers, ever, and it seems like a criminal enterprise or services designed to 'punish' or list complainants or victims? there are of course other 'fake' / non maintained and worthless blacklists, like abuse-att.net etc etc. but these generally do not go out of their way to punish victims... What is the best way to fight criminal enterprises that enter data streams and 'hide' / market etc as ethical service providers? Andre
